A larger version of the very popular TDI Law Enforcement Knife. In extreme close quarters encounters where a suspect is attempting to take an officer's handgun, or an officer cannot access his handgun, the TDI knife is available as a "last option" knife. When worn on the pant belt the entire unit - knife and sheath - is well concealed. Designed by John Benner, founder and owner of Tactical Defense Institute. Sold with hard plastic sheath that is fitted with flexible Cordura straps to mount to pant and duty belts, tactical vests, and more (see picture #2 above for sheath strap placement).
